VENTlLATING CARS.

SPECIFICATION forming part of Letters Patent No. 388,504, dated August28, 1888.

Application filed December 29, 1887. Serial No. 259.325.

To all whom it may concern:

Be it known that I, HIEAM PENOYER, a citi- .zen of the United States,residing at Tashington, in the District of Columbia, have in- Ventedcertain new and useful Improvements in Ventilating Cars; and I do herebydeclare the following to be a full, clear, and exact description oftheinvention, such as will enable others skilled in the art to which itappertains 1o to make and use the same.

My invention relates to certain new and useful improvements inVentilating carsrand it consists of a series of box-like frames havingopenings, swing-doors, suitable screens, and

over-caps, all of which are secured to the top of railroad-cars overopenings.

` The object of my invention being to automatically ventilaterailroad-cars from the roof of the same,l I attain this object by meansof 2o the peculiar construction and arrangement of the various parts ofmy invention, which will be more fully pointed outand described in thespecilieation and claims.

Reference being had to the drawings accompanying this application andforming part of the same, Figure l is a side elevation of a car havingmy invention applied thereto. Fig. 2 is a vertical sectional view of theventilator. Figs. 3 and 5 are detail views. Fig. 4 is a side 5celevation, partly in section, showing screen `embracing base ofventilator. Fig. 6 is a sectional view of slats and rod.

Similar letters refer to like parts throughout the drawings.

3 5 Referring to the drawings, A represents the top section of arailroad-car, that is provided with openings B, over which are securedthe ventilator-frames C. Said frames or chimneys extend upward from thetop of the car, and

4c are formed of any suitable material and size. They may be also formedround or square, as may be desired. The frames or casings C,being hollowand secured to the top of the car over the openings B,are provided withcaps D,hav

ing downward-projecting cylinders or Walls E, extending to the edge of adust Wire screen, F, within a short distance of the top of the car, theopposite edge of said screen F being (No model.)

secured to the top of the car and encircling the lower edge of the wallsof said caps.

Inclined supporting-strips F may be used to strengthen the structure;but these are not essential, as the wire fabric is of itself suicientlystrong where the structure is properly constructed and proportioned.

The caps D are formed to extend over and around the frames or casing C,forming an airspace, a.

The casings C are provided with/openings I), that are covered by wirescreens b', to keep out dust or dirt.

On the outside of the casings G,and in front ofeach opening b,are hungcurtains or swingblinds G, that are held at their upper ends to thecasings C above the openings b by means of staples c, that encircle theouter ends of rods d, that pass through the upper ends of said blinds G,the free ends of said blinds G being thrown outward by the outiiowingair rising from the inside of the car, and closing against any inliow ofdust-laden air or moisture, thus being automatic in their action.

At the openings B,and near the under edges of the casings G,are looselysecured a series of movable slats, e, that are endwise pivoted andconstructed to open and close against each other horizontally, acting asregisters to open or close the openings B. Said series of slats c isconnected to a longitudinal rod, f, secured to the under surface of thetop A of the car, and at either end of said rod f is secured a handle,f', within easy reach of the conductor. Said rodf being loosely held inplace by eyebolt g, it is readily moved longitudinallywby the operator,thus opening or closing the series of slats e at will.

The lower ends of the walls of caps D are provided with hooks h, thatare adapted to hook into eyes or staples h', secured to the npper edgeof dust-screen F, by which' means said caps D are removably held inplace.

The operation of the device is simple, and is readily controllable bytheconductor or other attendant from the interior of the car, who, bysimply grasping the handlef, may shift the rod f to either open or closethe slats e, as may be desirable or necessary to confine or to permitthe escape of the air in the car.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent, 1s-

l. A Ventilating-top for cars, consisting of a casing provided with sideopenings and secured to the top of a car over an opening in saidcar,s\vingblinds pivoted above said openings, and a cap or hoodextending overY said casing andprojecting downward belowsaid blinds, incombination with the encircling screen F and aseries of slats pivot-edat the said caropening and connected to an operating-rod, Ysubstantiallyas set forth.

2. In a car-ventilator, a casing provided with side openings havingscreens and secured over an opening in the top of the car, verticalswing-blinds hung, over said openings, a cap extending overrsaid casing,and a dust-screen connected thereto by hooks and eyebolts, incornbination with a series of slats connected to an
